This Biscayne is a total Q-ship – a monster tri-power 427 in a plain white wrapper. It has 400 horses that they’ll never see coming at your local drag strip. Forget muscle car characteristic stripes and hood scoops — this car is perfect for racers who want to fly under the radar until the lights go green. Then that screaming big-block will show them nothing but taillights.

This car has no options other than that 427 and a tinted windshield, which I think only adds to the appeal. The only thing that might tip off bystanders to what this car is are those big-block flags on the front fenders.

The seller says this car is a numbers-matching 427 car which was originally delivered with a 4-bbl carburetor. He added the Corvette tri-power setup, which he says bumped the power from the car’s original 385 to 400. The car itself has only 57,500 miles on the clock, and everything (other than the intake and carbs) is original, down to the TH400 automatic trans and 12-bolt Positraction rear end.

Options are few, which is typical of the lowest Biscayne trim level. There is no radio – only a block-off plate. No power steering, no power brakes, and poverty caps on the original steel wheels. But for a sleeper 4-door, that’s all perfect.

A total of 852 1967 full-size Chevys (Impalas, Caprices, Bel Airs, and Biscaynes) have sold on eBay Motors over the past two years. Average prices have ranged from $6,600 to over $16,000, depending on options and condition. This one’s originality and rare equipment may push its price even higher. See the listing here.
